nnnsrRING Application led February 28, 1929.`

The object rof the invention is .to ,provide a bed spring consisting both of a. frame kcomprising cross slats and helico-sp1ral springs, which Imay be readily disassembled .so as :to permit its being shipped in compact ioim to be lreassembled by the user; .to provide a bed springoct this character which is readily adjustableto suit any size 4bedstead on l which it Amay alternate elements in `links 14, the particular be employedf-that is to provide la frame adjustment to meet any size bed; `to Aprovide a construction .in Which the spring elements .which are detachably tied together are readily ,adjustable ,to `provide for the most satisfactory arrangement or spacing of those elements; and `to provide a manufacture fof the .character mentioned Which-is ,of simple `forni and therefore sus- ,ceptible of cheap production `and low `marketing cost.

With this object in viewthe invention .consists in construction and combination of parts of 4Which a` preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1` is a plan view rof the invention. Figure 2 is an enlarged detail plan View of a portion ofthe frame.

Figures 3 and 4 are sectional views on the planes'indicated by the lines 3-3 and 4 4 respectively of Figure 2. Y

Figure 5 is an enlarged detail plan view, partly in section, illustrating the connecting or tying means between vthe spring' elements.

Figure 6 is a perspective View of one of the spring elements. n

The invention comprises the side rails 10 and cross rails 1l, as Well as the spring` elements 12 which are spaced uniformly along` the cross rails and tiedtogether at their upper ends by crossing links 14 detaohably engagingthe upper convolutions of the springele- .ments By this arrangement, the spring elemen'tsare arranged in a plurality of trans verse series which are interconnected by the arrangement of the links providing for the interconnection of adjacent series.

The links 14 are in the `form of clips with .terminal bent ,back portions l'having routturned lips16, ythe bent back portions pro- `head board of the Serial No. 343,334.

viding loops which engage with the terminal convolutions of the spring elements, the lip 16 facilitating the attachment. Stops 17 are formed in the link elements in the loops to provide abutments for the engaged convolutions of the spring elements and preventing accidental displacement of the same.

The side rails 10 are of cross-sectionally Z-shaped form, of which the liange 1()a is vat right angles to the web andthe fiange 10b at a slight acute angle to the Web; The side rails are divided at an intermedia-te point in their length, so that the frame is thus composed oi" the head Vand foot sections A and B which are hingedly connected `together by reason thespring elements on the adjacent cross rails at the connecting ends of the sections. Thus one section of the frame may be raised or lowered and, if desired, the head section A may be folded over on the foot section B to permit cleaning, the folded position ot the top section making it possible then to slide the foot or bottom section towards the bedstead to clean around the foot section of the latter.

The terminal or end portions of the side rails are adjustable to fit the rails to various lengths of bedstcads, these terminal portions 18 being oi the same cross-sectional contour as the main portion of the side rails `but oit- .set as indicated at 19 to clear the cornerlblocles in some forms ot' Wooden bedsteads and also the round or curved ,portions of some forms ot iron bedsteads.

he extension sections 18 of the side rails have bolt and slot connections with the main sections, the latter being` formed with the slots 2O in the ianges 10a, certain of the bolts 21 which hold certain of the crossfrails to the side rails, passing through these slots and through holes in the corresponding flanges of the extensions. The cross `rails are secured to the side rails by `bolts 21 and in ened and the length adjustment thus maintained.

of the links 14 engaging Hrsn :ann SPR-ING COMPANY,

The frame is adjustable as to Width by reason of the cross rails 11 consisting of telescopically connected channel-shaped sections 1,1 and 11b the sliding engagement of which permits the proper spacing of the side rails to suit the particular Width of bed to which the frame is being adapted. The sections of the cross rails are depressed at the centers as indicated Aat 22 to leave the lower faces of the sections A in the plane of the lower edges of the flanges of the section B. This construction not only provides a strengthening means to prevent bending of the cross rails but also provides a form of rail particularly adapted to retain the spring elements l1 thereon.

The spring elements aie of helico-spiral form, the terminal bottom convolutions being extended to provide a hook member 23 which extends around the cross rail With the terminal or nose 2% lying against one side edge of the depressed portion 22. The spring elements may be placed to have the hook extend around the rail from either side, the terminal 24 lying against the side of the depressed portion. irrespective of Whether the spring is disposed to have the hook extend around one side or the other of the cross rail.

The upper terminal convolutions of the spring elements are adjustable to vary the diameter of these convolutions, this adjustment being provided by having the extremity of the Wire strands formed with an eye. 25 bent at right angles to the strand and embracing the strand of the next adjacent convolution. The eye snugly engages the connected strand of Wire and when held in a plane at right angles to the plane of the axis of the wire may be readily slid along the latter to increase or decrease the diameter of the terminal convolutions. The eifected adjustment is maintained, however, by reason of the tendency of the spring to swing the eye out of the normal plane which it is necessary that vit assume to provide reiative movement.

The improved spring is designed paiticularly for shipment in knocked down form to the place of use, the cross rails then being detached from the side rails and the spring elements nested in groups which may be done by inserting the convolutions of one spring in between the corresponding convolutions of another and so o nup t-a limited number. Attlie point of use,"'the side 'elements are adjusted Ato suit the length 'of the bedstead to be equipped, after which the cross rails are attached, having been adjusted by reason of their telescopic sections to the proper width of the bedstead. The bolts 21 serve as a means for attaching the cross rails to the side rails, those bolts passing through the slots 20 maintaining the longitudinal adjustment of the side rails. Thereafter the spring elements 11 are disposed on strand of which it is the cross rails, as previously described and as indicated in Figure 3, and the upper terminal convolutions adjusted, so that when the links la are attached there will be approximately a slight tension applied to these links. The structure then as a Whole is ready for reception of the mattress.

Ordinarily the ianges 10b of the side rails Will constitute the means for supporting the spring structure in a bedstead by engagement With the slat beads of a Wooden bedstead or the-side rails of an iron bedstead. In some cases, preferences may require that the spring structure be slung lower than this, in which case the hanger 26 indicated in dotted lines in Figures 2 and 4 will be employed. These hangers 26 are Z-shaped elements capable of being hooked over the side rails or slat bead 27 of a bedstead and under the flanges 10b of tlie side rails, as clearly shown in Figure 4.

The invention having been described what is claimed as new and useful is:

1. A bed spring comprising a longitudinally and laterally adjustable frame, spring elements mounted on said frame, and links connecting the upper terminal convolutions of said spring elements, said upper terminal convolutions having means to vary their diameters, to accord with the spacing of the spring elements on the frame.

2. A bed spring embodying a longitudinally and laterally adjustable frame comprising cross rails, spring elements seated upon and having detach able connections with said cross rails to permit uniform positioning of them according to the adjustment of the frame, and links interconnecting the upper terminal convolutions of said spring elements, said upper terminal convolutions having means to vary their diameters to accord With the spacing of the spring elements on the frame.

3. A bed spring embodying a longitudinally and laterally adjustable frame comprising cross rails, spring elements seated upon and having detachableconnections With said cioss rails to permit uniform positioning of them according to the adjustment of the frame,

and links interconnecting the upper terminal `convolutions of said spring elements, said upper terminal convolutions having the an eye bent at right angles to the strand and snugly embracing the strand of the next adjaeach of 4 formed provided with cent convolution to bind on the latter when f.

normally deflected out of a plane at right angles to the axis of the strand but to slide when deflected into a plane along the strand at right angles to the axis thereof.

4. A bed sisting of side rails composed of slidably `connected sections and cross rails spanning the side rails and composed of telescopically 'connected sections, the extremities of the ycross rails resting on the side rails and bolts extending through the extremities of the secspring comprising a frame contions of the cross rails and through the side rails, one of the sections of the side rails having a slot and the other a holt hole, the bolts of one of the cross rails extending through said slots and the holes of the side rails to maintain the setting of the sections of the side rails as Well as to retain said cross rail in position.
